PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 559,000, dated April28, 1896.

Application filed October 1, 1 892.

To @ZZ whom t may concern:

Be it known that I, JOHN II. STONEMETZ, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented a new and useful Improvement in Printing-Presses, of which thefollowing is a specification. a

The aim of this invention is to improve on the printing-press shown inLetters Patent 1o granted to me January 3, 1888, No. 376,053; and tothis end the invention consists of the device described and claimed inthis specification, and illustrated in the accompanying drawings, inwhich* Figure 1 is a sectional elevation of enough of such aprinting-press to illustrate my improvement. Figs. 2, 3, and 4 arediagrams illustrating the action of the inking-rollers, and Fig. 5 is adetail of part of the carriage z'o on an enlarged scale.

In the patent referred to I have shown a web-printing press in whichthere are two reciprocating impression-cylinders coacting with twostationary form-beds, and :means 2 5 for intermittentlyT drawing the webforward,

so that a sheet will be perfected at each move ment of theimpression-cylinders in either direction. In the patent I have shownformrollers as arranged on only one side of the 3o impression-cylinder,wherebya heavydeposit of ink will be made on the form, so that enoughink will be put on the form for two impressions. While this issufficient as regards newspaper or ordinary work, it may be desired insome cases to ink the form for each impression, and this inventioncovers a device whereby this may be nicely done with one set ofform-rollers.

In this present device I have shown a form 4o roller or rollers whichwill automatically move from one side of the impression-cylin der to theother, so that the form may be inked for every impression.

Referring to the drawings, and in detail,

A and B represent the reciprocating impression-cylinders, and C and Dthe form-beds with which the impression-cylinders eoact.

The impression-cylinders A' and B are mounted in the usual carriage orframing E,

Serial No. 447,542. (No model.)

and this carriagemay be reoiprocated by the mechanism shown in thepatent referred to. The web is led from the roll 1 around the stationaryroll 2, looping-roller 3, stationary 'driven to slowly draw the web fromthe looping-roller 11, and to feed the web from the roll 1 to thelooping-roller 3.

The looping-roller 11 is actuated by any suitable means to draw the webforward when the impression-cylinders are off the forms in eitherdirection, and with a machine organized as thus described a perfectedsheet will be printed for each movement of the impression-cylinders, andthe operation of these details is readily understood, and is describedat length in the patent referred to.

At the ends of the form-bed Care arranged ink-tables F and G, which arecurved, as shown, and on the ends of the bed D are ar. rangedsimilarink-tables H and I. Projecting up through each of theseink-tables is an ink-carrying roller 20, which has distributing-rollers21 and 22 bearing against the same, and each distributing-roller 21bears against a drum-roller 23, to which ink is supplied by theductor-roller 24 from a fountain 25. Thus an ink-supply is attached orused in connection with each ink-table.

Mounted on the shaft of each of the impression-cylinders are frames K,which have suitable projecting arms L, and in these frames K are mountedthe distributing-roller 30 and form-rollers 31, 32, and 33, as shown,and the frames K are free to swing or turn around the center of theimpression-cylinders. The distributing-rollers 30 may be positivelydriven from one of the gears, as N, arranged on the side of theimpression-cylinders by means of intermediates 40 and 41 and gear 42,fastened on the side of the same; and it will be seen that thedistributing-rollers 30 will' always be turned in an opposite directionfrom the impression-cylinders, whereby the form-rollers will be turnedin the same direction as the impression-cylinders, so that they will bealways turned to properly engage the forms.

The ink-tables are not formed on an arc of a circle, but on a curvesomewhat extended, so that as the impressioncylinders reverse in eitherdirection, during a slight portion of this movement, the form rollersmay be swung around the center of the cylinders, and thereby take asupply of ink fromv the ink-tables and move back on the opposite side ofthe impression-cylinders.

As shown, the form-rollers are arranged to drag` behind the impressioncylinders, although it is Wi-thin the scope of my invention and could beeasily arranged to have the form- `rollers move in front of theimpression-cylinders.

In Fig. 1 the impression cylinders are shown as just completing theirmovement to the right, and the web as being shifted, and the form-roller33 as just leaving the edge of theforms. Now, as theimpression-cylind`ers move still farther tothe right, the form-roller 33will leave the forms and will run down the ink-tables to the right ofthe form-beds, or, referring especially now to the case of thetormerollers used in connection with the impression-cylinder A, it willbe seen that they will drop to the position shown in Fig. 2. As theimpression-cylinder moves a slight distance still farther to the rightthe arms L will come against fixed projections M, and this will tend tomove the form-rollers past the center ofthe ink-tables, so that theformroller 33 willpass over the ink supplying roller 20, and so that thenest of form-rollers will be to the right of the impression-cylinder. onitsmovement tothe left, the nest of form rollers will draw up theincline of the inktable G to a position behind the impressioncylinder,and as this movement of the impression-cylinders continues theform-rollers 32 and 33 will pass over the form and will ink the form forthe next impression that the cylinder will make on its movement to theright.

It will be seen that as the impression-cylinders moveto the left theform-rollers 32 and will ink the forms, and that as theimpression-cylinders move to the right the form-rollers 3l and 33 willink the forms, the same action taking place when theimpression-cylinders reverse at their left-hand extremes. Thus theLforms are inked for each movement of the impression cylinders in eitherdirection.

In some cases I can omit the arms L and the stationary projections M andlet the formrollers change their position relatively to theimpression-cylinders by the momentum that they acquired and by droppingdown on the Now, as the impression-cylinder starts ink-tables; but Iprefer in most cases to use the arms and projections as described, sothat the form-rollers will be positively swung from one side to theother, and so that they cannot possibly cramp between the ink-tables andthe impression-cylinders as they commence to run up onto the form-beds.Thus it will be seen that the ink will be largely distributed on theform-rollers, and that the form-rollers will take up their ink byaslight movement of the impression-cylinders, as the ink-tables arecurved, as shown.

In some cases the form-rollers 3l and 32 can be omitted, and only oneform-roller, as

1roller 33, may be used, and any other means for supplying ink to theform-rollers may be used.

Thus it will be seen that I have invented an eflicient and simple inkingmechanism whereby the forms-will be inked for each impression of thecylinders if they print in both directions.

rlhe arrangement of parts and the details herein shownK and describedmay be greatly varied by a skilled mechanic without departing from thescope of my invention as expressed inl the claims.

Having thus fully described my invention, what I claim, and desire tolsecure by Letters Patent, issl.
